This invention relates to devices for supplying air to ice cansduring the freezingjof the water incthem in order toagitate the water to permit it to freeze free of impurigtiesa o i Referring to the accompanying drawings, which are made a parthereof and on which similar reference characters indicate similar parts i Figure 11isa perspective view showing a of my devicesapplied towan air lateral, ,U V v V 1 i Figure2, a section on an enlarged scale on line 2 '-2 ofFigurel, w

Figure 3, a side, elevation, and V Figurev l, a side elevation of the holding blocln V In the drawings numeral lOindicates an air supply pipe which maybe-connected to a source of-air under-pressure,: not shown. In order to hold it in position above the ice cans, this pipe may have one or more blocks 11 secured thereon by means of set screws 12. The block 11 is slotted at each side as shown at;13, and tapered so that the lower end is not as-wide as the upperend and fits in a notch in oneof the partitions between the Y ice cans. The block 11 prevents axial as well asjtu-rningmovement'fof the pipe 10. The pipe 10 lies in notches 14c in the partitions 15. A strap of iron 16 is bent over and secured to the pipe 10 by means of a bolt 17. The lower end of the strap 16 is bent into U- shape, as shown at18. The sides of the U are slotted at 19 to receive the small ends 20 of i an enlarged cylindrical swivel 21 formed as a part of the nozzle 22. The swivel 21 has a short pipe 23 entering it atone side and a relatively long end 22 at the other side, which is'threaded at 24. The lower end 25 otthe pipe22 is smaller than the main portion of this pipe to provide a shoulder at 26. A short rubber tube 27 is slipped upon the pipe 22 and held by the threads 24. A relatively long metal tube 28 is slipped up around the metal tube 25 within the rubber tube 27. Preferably a small metal ring 29 is inserted within 7' together :with the parts cooperating with it vice without departing from the spirit of the 'inventionand'therefore I do not limit myseli cated in the appended claims.

side of the pipe 10 and extends a'short distanceQwithout the pipeand has a short rubber tube 31 pressed thereomthelower end of the tube'31 being secured to the short end 23 which extends out from the swivel 21. a A latch 32 is, pivoted at 33 to the member 16 v and has its lowerend formed intoaU-shaped catch which fits'around the U-shaped portion 181011 the lower endrof the member 16." The ends 34 of the catch 32 fit just above thetrun .60 nions 20 on the swivel 21 to hold this in posi-' 'tion but to permit thepipe 28 together with 7 its parts to swing on the trunnions2Q; Obviously any number of suspended: pipes 28' '65 may be attached to-any one airlateral 10.

WVhile the pipes 28 have been shown as sus pended to swing laterally of the ice cans obviously they could be suspended to swingthe long way of the cans by having the trunnions 20 mounted parallel with the pipe 10 instead of at right angles tothe pipe 10, as shown. i From the foregoing, description it will be apparent that the air lateral lO-together with- A 2111012 its connections may be lifted Out of the cans. ,This'is ordinarily done just before the ice cakesin the cans freeze shut. By means ofthe block 11 the tube 10 is positioned sothat the pipes 28 will swing centrally of the ice can." J

In case any of the-tubes 28 become frozen in the ice cake they may be slipped out of the rubber tubes27 andflater removed from the ice cake, By pushing back the latch 32 the swivel 21 may beilifted out of its supporting bracket and the parts separated so as to be 'cleanedif necessary. I V 'The'wholeassembly is s mple, easily put into position and taken out, easilytaken apart to clean it necessary and efficient, operating to deliver air into the center ofthe forming ice cake. v "5 s It will be obvious tothose skilled in the art that various changes may be made in my deto what is shown in the idrawings andidescribed inthe specificatlon, but only as indi- V Having thus fully descrlbed mysaid in and turning movement, and a plurality of air supplying pipes suspended from and at intervals along said pipe, said supplyingpipes being permitted to swing in one plane only, substantially as set forth.

a block secured upon the pipe engageable with a notch in one of the partitions to hold the ipe against axial andwturning movement, a urality of air supplying conduits suspended from said mainsupply pipe, means or permitting these said conduits to swing in one direction laterally of th'ecans but to be held against swinging in any other direc ticn, substantially as set forth.

4. Means for supplying air to freezing ice cans comprising a main supply pipe, means forholding it against axial and turning movement above the ice cans, brackets secured on said pipe, a plurality of pipes suspended from said brackets, said pipes being flexibly connected to the said main pipe, substantially as set forth.

5. Means for supplying air to freezing ice cans comprising a main supply pipe, means for holding it against axial and turning movement above the ice cans, a plurality of lraokets secured in spaced relation on said pipe, a plurality of pipes suspended from said brackets, said pipes being flexiblycon- :neoted to the said main pipe, and means on the suspended pipes for limiting their to swing in one direction only, substantially as set forth.

7. Means for supplying air to freezing ice cans comprising a main supply pipe, a plurality of depending supply pipes positioned to hang in the center of each ice can, said depending supply pipes comprising a'swivel joint, means for mounting it to swing in one direction in the said ice cans, a flexible con-. nection between the swivel joint and the main supply pipe, :1 rubber sleeve positioned on the said swivel joint, and a metal tube positioned within the said rubber sleeve and frictionally held therein, substantially as set forth.

8. Means for suppl ing air to ice cans through a tube with a ip pint comprising a tube, aru bber hose stripped over one end of the tube, a ring holding open the mouth of the hose, another tube adapted to enter the ring and being pushed over the first tube and within the rubber hose to make a substantially air tight connection between tubes and a substantially connection as to bending at the joint substantially as set forth.
